Articles of Association explained: meaning, legal function, and role in UK company formation under the Companies Act 2006. Guide to governance rules, shareholder rights, director powers, Model Articles, and corporate structure for new companies in England and Wales.

The Articles of Association are a core constitutional document for every company formed in the United Kingdom. They set out the internal rules governing how a company is run, how decisions are made, and how powers are allocated between directors and shareholders.
When a new company is incorporated under the Companies Act 2006, the Articles form part of the legal framework submitted to Companies House and become binding on the company and its members. Unlike the Memorandum of Association, which primarily records the intention to form a company, the Articles regulate its ongoing internal governance.
This article explains what the Articles of Association are, their legal function, and their practical importance in the formation and operation of a new company.
What the Articles of Association Are
The Articles of Association are a legally binding set of rules that govern the internal management of a company. They operate as a contract between:
- The company
- Its shareholders (members)
- Its directors
Under Companies Act 2006, every company must have articles of association when it is formed. If no bespoke articles are provided, the company automatically adopts the Model Articles prescribed by law.
The Articles are submitted to Companies House during the incorporation process.
Purpose of the Articles of Association
1. Governing internal company operations
The primary purpose of the Articles is to regulate how the company operates internally. This includes rules on:
- Appointment and removal of directors
- Director powers and decision-making authority
- Shareholder voting rights
- Dividend distribution
- Board meetings and procedures
They ensure that the company has a clear governance structure from the moment it is formed.
2. Defining rights and obligations
The Articles define the rights and responsibilities of:
- Shareholders (members)
- Directors
- Company officers
This includes how control is exercised within the company and how disputes are resolved internally.
3. Providing legal certainty
Because the Articles form a binding agreement, they provide legal certainty in company operations. If disputes arise, courts and tribunals may refer to the Articles to determine:
- Whether directors acted within their powers
- Whether shareholder decisions were valid
- Whether proper procedures were followed
Legal Status of the Articles of Association
The Articles have contractual force under UK company law. This means:
- They are binding on the company and its members
- They can be enforced in court
- They operate as an internal rulebook for governance
They do not override statutory law but must operate within the framework of company legislation.
In practice, they form part of the company's constitutional documents alongside the Memorandum of Association.
Types of Articles of Association
1. Model Articles
Most new companies adopt the Model Articles, which are standard templates provided by law. These cover:
- Basic director powers
- Decision-making procedures
- Shareholder meetings
- Administrative rules
Model Articles are suitable for many small and medium-sized companies.
2. Bespoke Articles
Some companies adopt tailored Articles to reflect specific needs, such as:
- Investor rights in start-up companies
- Complex shareholder arrangements
- Corporate group structures
- Restrictions on share transfers
Bespoke Articles are often used in commercial transactions, joint ventures, and investment-backed companies.
Function of Articles in a New Company
1. Establishing governance from incorporation
From the moment of incorporation, the Articles determine how the company is controlled. This includes:
- Who has authority to make decisions
- How directors are appointed
- How shareholder resolutions are passed
2. Regulating share structure and ownership
For companies limited by shares, the Articles regulate:
- Issue and transfer of shares
- Rights attached to different share classes
- Voting rights per share
- Dividend entitlements
This is critical in determining ownership control.
3. Managing director authority
The Articles define:
- Scope of director powers
- Limits on decision-making
- Requirements for board approval
- Procedures for conflicts of interest
This ensures directors act within a defined legal framework.
4. Protecting minority shareholders
Well-drafted Articles may include protections such as:
- Pre-emption rights on share transfers
- Voting thresholds for major decisions
- Restrictions on dilution of shares
- Rights to appoint directors
These provisions are particularly important in investment and joint venture companies.
Articles vs Memorandum of Association
A common area of confusion is the distinction between these two documents.
Articles of Association
- Governs internal management
- Sets rules for directors and shareholders
- Can be amended after incorporation
- Actively used in company operations
Memorandum of Association
- Records intention to form a company
- Used only at incorporation stage
- Cannot be changed after formation
- Historical legal document
The Articles are therefore the operational rulebook of the company.
Legal Effect in Disputes and Litigation
The Articles are frequently examined in legal disputes, including:
- Shareholder disputes in the High Court
- Director misconduct claims
- Breach of fiduciary duty cases
- Company liquidation and insolvency proceedings
Courts rely on the Articles to determine whether company procedures were properly followed and whether decisions were legally valid.
Amending the Articles of Association
The Articles can be changed after incorporation, but only through a formal process:
- Special resolution of shareholders (usually 75% approval)
- Filing amended Articles with Companies House
- Compliance with statutory requirements
Certain amendments may also be subject to legal challenge if they unfairly prejudice minority shareholders.
Common Legal Issues
1. Conflicts between Articles and shareholder agreements
Shareholder agreements may conflict with Articles. In legal disputes, Articles generally take precedence in matters affecting company governance.
2. Poorly drafted Articles
Weak or generic Articles may lead to:
- Governance uncertainty
- Director disputes
- Investor disagreements
- Litigation risk
3. Failure to follow Articles
If directors or shareholders act outside the Articles, decisions may be:
- Invalid
- Challenged in court
- Subject to injunctions or claims
Practical Importance in New Companies
The Articles of Association are critical because they:
- Define how the company is controlled from day one
- Establish investor and shareholder rights
- Reduce the risk of internal disputes
- Provide a legal framework for decision-making
- Support due diligence in investment and financing
They are one of the most important documents in company formation and ongoing governance.

Key Takeaways
The Articles of Association are the internal rulebook of a UK company, setting out how it is governed, how decisions are made, and how powers are distributed between directors and shareholders. They are legally binding, submitted at incorporation, and form the foundation of corporate governance under the Companies Act 2006.
For new companies, the Articles are essential in defining ownership structure, protecting shareholder rights, and ensuring legal clarity in management and decision-making. Properly drafted Articles help prevent disputes and provide a stable framework for business operations.
